Benefits of technology

"The present invention provides a modified low-concentration atropine solution for preventing myopia progression. This solution has excellent preventing efficiency with less side-effects. The atropine concentration is less than 0.1% (w / w) and preferably 0.05% (w / w). The preparing method involves diluting the atropine ingredient to obtain the low-concentration atropine solution. The technical effects of this invention are to provide an effective and safe solution for preventing myopia progression."

Problems solved by technology

Once children have myopia, the myopic degrees continuously increase until the end of adolescence so that those children are in great danger to suffer high degree myopia.
Therefore, efficiently preventing myopia progression in children is an important issue.
Although powerful 1.0% atropine solution is used in many countries and 0.5% atropine solution is commonly used in Taiwan, those solutions still have some drawbacks in clinic application because patients will have photophobia that disorders their daily outdoor activities.
Therefore, the compliance is poor and dropout rate is correspondingly high.

Embodiment Construction

[0015] A low-concentration atropine solution for preventing myopia progression in accordance with the present invention comprises atropine concentration less than 0.1% (w / w).

[0016] As described in the foregoing description, the efficient administration of atropine solution is surely regarded to contain 0.5% (w / w) atropine concentration and never assumed to contain the atropine concentration less than 0.1% (w / w).

[0017] In the present invention, the lower-concentration atropine solution for preventing myopia progression is defined to have the atropine concentration less than 0.1% (w / w) and has been proved to possess excellent compliance better than ones with 0.1% (w / w) and 0.25% (w / w) atropine concentrations. Preferably, the range of the atropine solution is from 0.001% (w / w) to approximate 0.1% (w / w). Experiments are shown and illustrated as the following descriptions and comparison tables.

[0018] Firstly, clinic patients were observed to have photophobia and poor compliance in adm...

Abstract

A low-concentration atropine solution for preventing myopia progression contains an atropine concentration less than 0.1% (w / w). Preferably, the atropine concentration is 0.05% (w / w) in optimal situation. The low-concentration atropine solution in treatment causes less photophobia and systemic side-effects to patients and has excellent compliance to reduce damages from ultraviolet and hazard blue light and to avoid visual morbidities such as cataract and retinal macula lutea deterioration.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a low-concentration atropine solution for preventing myopia progression, and more particularly to a low-concentration atropine solution substantially relative to human medication to prevent exacerbation in myopia progression. [0003] 2. Description of Related Art [0004] Myopia is a crucial ophthalmic morbidity, especially with high myopic diopter, that causes many complications such as youth cataract, glaucoma, retinal detachment, macular hemorrhage, and retinal degeneration. In Taiwan, myopia is the second factor which causes blindness in aged people so that prevention for myopia progression is important. Preventing high myopia has to be undertaken since childhood. Asian children suffer myopia increase 75 to 100 degree (0.75 to 1 Diopter) per year and western children the same increase 50 degree (0.5 Diopter) per year. Once children have myopia, the myopic degrees continuously increa...
